XIaomi Redmi 7 bootloop

[Mirco]

Bootloop after a failed unlock bootloader. Bootloader recovery through isp does not help. What other options can be used to restore the bootloader?

[Legija]

Erase devinfo partition and reflash persist with stock file.

[Mirco]

did not help. hanging on port 9008.

[Legija]

What did you do exactly ?

[Mirco]

I flashed files to unlock the bootloader. After that, the phone hung on the 9008 port. Tried to restore the bootloader - did not help.. Erase devinfo partition and reflash persist with stock file. The phone still hangs on the 9008 port.

[Legija]

Can You attach those files here ?
You probably need to recalculate gpt now - emmc plugin, parse connected - adjust gpt.

[Mirco]

Here are these files

[Legija]

So you flashed rawprogram0 and did not adjusted GPT afterwards. Just adjust gpt and it should work.

[Mirco]

launched the bootloader recovery again, after that parse connected - adjust gpt. Does not help all the same hanging 9008 port. And I can not flash the firmware because there is none prog_emmc_firehose 8953 ddr no authorized. And to flash the full firmware through the ISP, it will be flashed for 3 days. But I think I'm running out of options.

[Legija]

But wait, how did you flashed unlock files in first place ?
That sounds weird that it stays in 9008 . . . Must be possible to fix, as i know there is patched firehose for this model.

[Legija]

I reworked repair pack, so please do this:
1. Download riffpkg and exe from beta sw folder and replace existing files:
Link
(redmi 7 onclite riffpk and jtagmanager.exe)
2. Click resurrection, select repair bootloader and let it finish,
3. Click resurrection again, select unlock bootloader and let it finish
4. Carefully inspect phone board for broken or shorted resistors or solder points, fix if anything damaged
5. Test phone for fastboot mode, but first remove wires.

[Mirco]

Everything was done as you wrote. All the same 9008 port. I inspected the board, found no damage anywhere. I didn't find the patched firehose for this model

[Legija]

There could be three reasons for this:
1. Wrong model
2. Damaged HW
3. Wrong region

There could be also fourth, and it's version mismatch but I think that there is no newer version than I used. Maybe You can find out exact region/version etc data ? Do you get anything on android info button in plugin ?

by the way I have 2 more similar devices, maybe it is possible to read some sections from them and to write in this non-working.
